To all whom it may concern: Be it known that I, ERNEST K. ARM- a citizenof the United States, residing at Millersburg, in thecounty of Holmesand State of Ohio, have invented certain new and useful Improvements inHair-Pins, of which the following is a specification.

My invention relates to improvements in hair pins, and more particularlyto that class or type which is formed of a single length of wire bentupon itself to form a two-armed or forked hair pin, such as is in commonuse, the present embodiment of this invention being designed not only asa substitute for but an improvement on such pins, as will hereinaftermore fully appear. The primary object of the invention is to provide agenerally improved hair pin of this class, which will be exceedinglysimple and eflicient in use.

A further object of the invent1on is to improve the construction andarrangement of the arms or prongs of the improved pin whereby theimproved pin may be more readily inserted, as well as removed, from thehair of the wearer.

A still further object is the provision of improved anchor shouldermembers terminating in spaced prongs, the common planes of the latterbeing elf-set to one side of the common plane of the shank or handlememhere, the shank shoulder and prong members being of similar form andarrangement so as to extend parallel to each other when in closed orcompressed position through the improved operating loop head, therebygreatly facilitating the insertion and removal of the hair pin in actualservice.

A still further object is the provision of an improved handle oroperating loop head whereby the arms or prongs may be readily compressedinto parallel relation to each other for insertion in the hair of thewearer, and after being inserted may be readily released or expanded forbeing anchored or securely retained therein, and when desired may becompressed into released or parallel relation to each other for readyremoval from the hair.

With the above mentioned and other ends in view, the invention consistsin the novel construction, arrangement and combination or parts,hereinafter described, illustrated in one of its embodiments in theaccompanying Specification of Letters Patent.

HAIR-PIN.

Patented July 8, 1919.

Application filed October 1c. 1918. Serial No. 258.477.

Fig. 2, a similar view, illustrating the manner in which the arms orprongs are compressed into parallel relation to each other through theimproved operating loop head in the act of inserting the same into orremoving the same from the hair of the wearer.

Similar numerals of reference designate like parts throughout all thefigures of the drawings.

The improved hair pin comprises a single length of wire bent upon itselfmidway between its ends forming a handle loop head 1, carrying spacedarm or shank members 1, the latter terminating in anchor shoulders 1',extending in a like direction and to one side, said shoulder membersterminating in off-set prongs 1, the common axial planes of said olf-setprongs 1, being at one side of the common axial plane of said spaced armor shank members 1, as shown most clearly in the drawings.

As a means of causing the shank shoulder and prong members to normallyoverlie or extend parallel with each other when closed or compressedthrough the medium of the operating handle loop head 1, as shown mostclearly in Fig. 2, of the drawings, for the ready insertion and removalof the hair pin in the hair 2, of the wearer, the shank shoulder andprong members are of like form and extend in a like direction, and itwill be obvious upon reference to Fig. 1, that when the shank shoulderand prong members are released by the handle loop head and permitted toexpand into their normal expanded or anchored position, as shown in Fig.1, of the drawings, the anchor shoulders 1", will interlock with thehair so as not only to prevent the outward movement of the hair pin, butsecurely maintain the same in proper position as against inwardmovement.

It will also be observed that the handle loop head 1, is of such formand arrangement with respect to the shank and prong members as to enablethe latter to be readily manipulated through the thumb and finger of thehand, as shown most clearly in Fig. 2, of the draWings, such handle loophead being of convenient form to be readily grasped by the hand in theact of insertion and. .removal.

From the foregoing description, taken in connection With theaccompanying draws ings, the operation and advantages'of my inventionWill be readily understood.

Having thus describedone of the embodiments of my invention, What Iclaim and desire to secure by Letters Patent, is,-

1...A hair pin, comprising shank members terminating at one end in aprong operating loop head and at the other in anchor shouldersterminating in off-set prongs having their common axial plane disposedWholly at one side of andsubstantially parallel With the common axialplane of said shank members, said shank shoulderv and ron members overlainc and extendin a H b parallel with each other When compressed by saidoperating loop head for insertion into and removal from the hair of'thewearer.

2. A hair pin, comprising shank members terminating at one end in anenlarged prong F operatlng loop head and at the other in an chorshoulders the latter being spaced a substantial distance from said loophead and ter- 'minating in ofi-set prongs having their common axialplane disposed Wholly at one side of and substantially parallel With thecommon axial plane of said shank members, said shank and prong membersnormally extend- In testimony whereof I. have afiixed my signature.
